UNIVERSAL JOINT.

Specification of Letters Patent.

Patented May 9, )1911.

Application tiled April 29, 1910. Serial No. 558,467.

^ they are practically contained within a chamber adapted to serve as a lubricant reeeptacle.

Third, to provide an improved universal joint which is capable of transmitting heavy loads, and one which is, at.-

the same time, comparatively simple and compact. Fourth, to provide -an improved universal joint embodying these advantages in which the parts are quite simple in form and easily assembled.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.l

We accomplish the objects of our invenIk tion by the devices and means described in the following specification.

The structure described constitutes one effective embodiment of our invention..

Other embodiments would be readily devised by those skilledin the art.

The invention is clearly defined and pointed out in the claims. y

A structure constituting an effective and vpreferred embodiment of the features of our invention is' clearly illustrated in the accom-- .panying drawing, forming a part of this specification, in which:

view of the ball member 3 and the journal nais disassembled. lFig. 5 is a' pin member 14 in their assembled relation.l

Fig. 4 is a perspective view of the journal pin member 14 and the-bushings for its jourperspective view of the ring bearing member 8.

In the drawings, similar reference char acters refer to similar parts throughout the several views.

Referring to the drawing, 1 and 2 represent shafts in connection with our improved joint, as illustrated. The vball joint member 3 is provided with a hollow shank 4 in which the shaft 2 is slidably arranged. The shaft 1 is coupled to the socket member 5 by a coupling member 6. The socket' member 5 is adapted to receive the ball member3, and has a seat 7 for the ring-like bearing member 8 which co-acts with the inner portion of the ball member. The ring bearing member is retained in its seat bythe coupling member 6, which is provided with an annular rib 9 which fits into the seat 7 for the bearing member 8, as clearly appears in Fig. 2.

The socket member 5 is vided with an outwardly-projecting flange 10 at its outer end and the coupling member G is provided with a couplingl flange 11, the flanges being adapted to receivethe bolts 12 whereby they are detachably secured together. The ball and socket members 3 and l5 and the. coupling member 6 are preferably formed as to constitute a lubricant receptaele or chamber, the coupling member 6 being provided with a lubricant opening which is normally closed with a screw 13. v

A journal pin member 14 is provided, having a bearing therein for' the journal pin 15, which is carried by the socket member 5,' (see Fig. 2), the pin vbeing provided with a head 16 at one end and a nut 17 at the other. The journal member 14 is arranged in the ball member which is provided with a radial slot 18, as is illustrated in the drawing. -'l`hejournal,member 14 is provided with journals 19, preferably' formed integral therewith, which are provided with suitable bearings in the ball member. These bearings are provided by forming slots 2Q transversely to the slot 18 and seats 2l at the inner ends of the slots for the bushings 22 the diameter ot thebushings being greater than the Width of the slots 20, andy when they' are inserted in their seats, the journal member is retained in the ball'- member.

The bushings are provided with lubricant holes or passages and the journalmember lll with a lubricant passage 24 so that the journals 1.9 and the journal pin l5 are eil'ectively lubricated. This arrangement ot parts also serves as a means of supplying lubricant to the slip connection between the shaft 2 and the shank Lil the ball member.

Oui' improved joint, as ivill be obvious, is a combination of ball and. socket and journal joints. lt is capable olf tansmitting very heavy loads and the wear and strain on the parts is minimized. rlllie parts of the structure are companatively simple and eoonomical to produce and are very easily assenr bled or disassembled. ln dis ssembling the joint, lthe coupling member G is released from the socket member 5 and the journal pin l5 removed, when the parts are entirely' freed.

live have illustrated and described our improved joint in detail in the form' in which We have embodied the same, although iveare aivare that it is capable of considerable variation in structural details without departing :trom our invention. This form illustrated has, however, va 'ions structural advantages, and We desire to be understood as claiming the same specilically in the form illustrated, as well as broadly vvithin the scope of the appended claims.
